Switching access to backup system
Perform a cluster switchover when you want a backup system to access the switchable device containing an independent disk pool.
In a multisystem clustered environment that uses switchable independent disk pools, an independent disk pool can only be accessed by one node at a time. Up to date access to a switchable independent disk pool is managed through the switchover function within the cluster.
To switch access from the current node in the cluster to the first backup node:
- The switchover may have already made the current node unavailable. If not, then from the current node, make a disk pool unavailable (vary off).
- Switch the independent disk pool to the first backup cluster node by performing a switchover in the cluster.
